Which one of the following does not contribute to the conservation of water?

Options

A. Waste water treatment
B. Wasteland development
C. Watershed protection
D. Rainwater harvesting

Answer

To determine which option does not contribute to the conservation of water, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Water Conservation**: Water conservation refers to the practice of using water efficiently to reduce unnecessary water usage. It involves various methods and practices that help in preserving water resources.

2. **Analyzing Each Option**:
- **Option 1: Waste Water Treatment**: This process involves treating used water (wastewater) so that it can be reused or safely released into the environment. This contributes to water conservation by recycling water.
- **Option 2: Waste Land Development**: This typically refers to the process of converting unproductive land into productive land. While it may have environmental benefits, it does not specifically relate to conserving water resources.
- **Option 3: Waterside Protection**: This involves protecting water bodies (like rivers, lakes, and wetlands) from pollution and degradation. It helps maintain the quality and quantity of water, thus contributing to conservation.
- **Option 4: Rainwater Harvesting**: This is a method of collecting and storing rainwater for reuse. It directly contributes to water conservation by capturing water that would otherwise run off and be lost.

3. **Identifying the Correct Answer**:
- Among the options, **Waste Land Development** (Option 2) does not directly contribute to the conservation of water. The other options focus on managing and preserving water resources.

### Conclusion:
The option that does not contribute to the conservation of water is **Option 2: Waste Land Development**.
